1. The Colorado River carves land in Arizona to form the Grand Canyon- Erosion

2. Cracks form in a sandstone wall surrounding a house- Weathering

3. A marble statue near the science museum is changing color due to rainfall- Weathering

4. After a rainstorm, soil and rock pieces litter the roadways- Weathering

5. The sand dunes in the Sahara Desert are changing shape- Weathering

Explanation:

Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

if you mean hydrogen and oxygen then water is the product
